ShenZhen HaoQiCore introduces a high-precision power consumption and energy monitoring chip PAC1934, which is used in conjunction with Microchip software drivers and is fully compatible with the energy estimation engine (E3) built into the Windows 10 operating system. On Windows 10 devices, its measurement accuracy is as high as 99%. Microchip‘s PAC1934 and Windows® 10 drivers combined with Microsoft‘s E3 service improve battery usage measurement accuracy by 29% for various software applications.

Jessie Labayen, Principal Program Manager at Microsoft, said: "Microchip‘s PAC1934 has a very wide measurement range and can accurately measure the power consumption of the display, CPU, storage, network, overall and other system components. This is a Windows 10 energy estimation engine software evaluation. A major improvement in functionality, and a major step forward for system providers and everyday users."

The PAC1934 is designed to measure voltage rails as low as 0V and as high as 32V. It is this capability that enables the chip to accurately measure a wide range of power consumption, from simple core processing unit (CPU) tasks to software running on devices connected via a USB Type-C™ connector. The PAC1934 is a quad-channel device that supports 16-bit power measurement and has a 17-minute accumulation register, ideal for determining power consumption and energy usage without adjusting voltage or current ranges.

Bryan Liddiard, vice president of marketing for Microchip‘s Mixed-Signal and Linear Products Group, said:

Windows 10 devices need accurate and easy-to-use power monitoring ICs that display the most accurate information on software power consumption. Consumers don‘t necessarily know that Microchip is behind the scenes, but thanks to this new device, people around the world will have more reliable battery life statistics.

This device has features that make it an integral part of future software updates. Bidirectional measurement is supported - meaning battery charging and discharging can be measured at the same time, which is ideal for the upcoming USB Type-C charging topology, which will have a wide range of applications. In addition, the device can be used as a standard high-side current sensor for server, networking, automotive and industrial applications. Microchip is also actively working to support various applications of the PAC1934 in Linux®.

The above is the relevant introduction of the chip PAC1934, I hope it can help you.
